so i have the Xbox one version, along with both dlc's... breaking ground and making history. i find i have all the parts i need with all these dlc's and the base game... i never use mods or ever will. i like the challenge of using only stock parts. heck the breaking ground dlc gives me all the robotics i need and a kal controller to fully automate everything... i find that I'm using my brain more and more like this, like a true engineer would have to. having all these mods and extra parts are unnesercery.. I've built a star-ship replica using only stock parts, with the six engines and i can switch off the 3 main launch engines and land the starship with the 3 inner engines, just like the real starship. i have built the super heavy booster with only stock parts and its spot on. you just have to spend a bit of extra time problem solving and thinking outside of the box.. check out my YouTube channel.. search "able wire ksp1 engineering" its the first white logo with the uk flag colours and able wire space agency written on it. to see what i have achieved so far! I've only been playing for 9 months so far on and off, not ever day all day. but I've made some good decent rockets etc.
